Si loo falanqeeyo taraafikada shabakadda, waxaa lagama maarmaan ah in baakadda shabakadda loo diro NTOP/NPROBE ama Qalabka Amniga iyo La socodka Shabakadda ee ka baxsan band. Waxaa jira laba xal oo loo heli karo dhibaatadan:
Muraayadda Dekadda(sidoo kale loo yaqaan SPAN)
Taabashada Shabakadda(sidoo kale loo yaqaan Taabashada Nuqulka, Taabashada Isku-darka, Taabashada Firfircoon, Taabashada Copper, Taabashada Ethernet, iwm.)
Kahor inta aan la sharxin farqiga u dhexeeya labada xal (Port Mirror iyo Network Tap), waa muhiim in la fahmo sida Ethernet u shaqeeyo. 100Mbit iyo wixii ka sareeya, martigeliyayaashu waxay badanaa ku hadlaan laba-laab buuxa, taasoo la micno ah in hal martigeliye uu diri karo (Tx) oo uu heli karo (Rx) isku mar. Taas macnaheedu waa in fiilo 100 Mbit ah oo ku xiran hal martigeliye, wadarta guud ee taraafikada shabakadda ee hal martigeliye uu diri karo/heli karo (Tx/Rx)) waa 2 × 100 Mbit = 200 Mbit.
Muraayadda Dekeddu waa nuqulka baakadaha firfircoon, taasoo la macno ah in aaladda shabakadu ay mas'uul ka tahay nuqulka baakadaha dekedda muraayadda leh.
Taas macnaheedu waa in qalabku uu shaqadan ku qabto isagoo adeegsanaya kheyraad (sida CPU), labada jiho ee taraafikadana waxaa lagu celin doonaa isla dekedda. Sida hore loo soo sheegay, isku xirka duplex-ka oo buuxa, tani waxay la macno tahay in
A - > B iyo B -> A
Wadarta A kama badnaan doonto xawaaraha shabakadda ka hor inta aysan dhicin khasaaraha baakadda. Tani waxay sabab u tahay inaysan jirin meel bannaan oo lagu koobi karo baakadaha. Waxaa soo baxday in muraayadda dekeddu ay tahay farsamo aad u fiican maadaama ay samayn karaan beddelaadyo badan (laakiin ma aha dhammaantood), sababtoo ah inta badan beddelaadyada leh cilladda luminta baakadda, haddii aad la socoto xiriir leh culays ka badan 50%, ama aad muraayadda dekedaha ku dhejiso deked dhakhso badan (tusaale ahaan muraayadaha dekedaha 100 Mbit ee dekedda 1 Gbit). Intaa waxaa dheer, muraayadda baakadda waxay u baahan kartaa is-weydaarsiga ilaha beddelaadda, taasoo laga yaabo inay ku shubto qalabka oo ay keento in waxqabadka beddelaaddu uu hoos u dhaco. Ogsoonow inaad ku xidhi karto 1 deked hal deked, ama 1 VLAN hal deked, laakiin guud ahaan ma koobi kartid dekedo badan 1. (Sidaa darteed muraayadda baakadda) ma maqan tahay.
Shabakad TAP (Barta Helitaanka Terminalka)waa qalab qalab oo gebi ahaanba aan firfircoonayn, kaas oo si dadban u qaban kara taraafikada shabakadda. Waxaa badanaa loo isticmaalaa in lagu kormeero taraafikada u dhaxaysa laba dhibcood oo shabakadda ah. Haddii shabakadda u dhaxaysa labada dhibcood ay ka kooban tahay fiilo jireed, TAP shabakadeed ayaa laga yaabaa inay tahay habka ugu wanaagsan ee lagu qaban karo taraafikada.
Shabakadda TAP waxay leedahay ugu yaraan saddex dekedood: deked A, deked B, iyo deked kormeer. Si loo dhigo tuubo u dhaxaysa dhibcaha A iyo B, fiilada shabakadda ee u dhaxaysa barta A iyo barta B waxaa lagu beddelaa laba fiilo, mid wuxuu aadayaa dekedda A ee TAP, kan kalena wuxuu aadayaa dekedda B ee TAP. TAP wuxuu dhaafaa dhammaan taraafikada u dhaxaysa labada meelood ee shabakadda, si ay wali isugu xiran yihiin. TAP waxay sidoo kale nuqul ka sameysaa taraafikada dekedda kormeeraha, taasoo u suurtagelinaysa qalabka falanqaynta inuu dhegeysto.
TAP-yada Shabakadda waxaa badanaa loo isticmaalaa aaladaha la socodka iyo ururinta sida APS. TAP-yada waxaa sidoo kale loo isticmaali karaa codsiyada amniga sababtoo ah ma aha kuwo aan la arki karin, laguma ogaan karo shabakadda, waxay la macaamili karaan shabakadaha laba-geesoodka ah iyo kuwa aan la wadaagin, badanaana waxay dhex mari doonaan taraafikada xitaa haddii tuubooyinku ay joojiyaan shaqada ama ay waayaan korontada.
Maadaama dekedaha Network Taps aysan helin laakiin ay gudbinayaan oo keliya, badhanka ma laha wax tilmaam ah oo ku saabsan cidda gadaasha dekedaha fadhida. Natiijadu waxay tahay inay baakadaha u gudbiso dhammaan dekedaha. Sidaa darteed, haddii aad qalabkaaga kormeerka ku xirto badhanka, qalabkaasi wuxuu heli doonaa dhammaan baakadaha. Ogsoonow in habkani shaqeeyo haddii qalabka kormeerka uusan wax baakad ah u dirin badhanka; haddii kale, badhanka wuxuu u qaadan doonaa in baakadaha la taabtay aysan ahayn qalabkaas. Si aad taas u gaarto, waxaad isticmaali kartaa fiilo shabakadeed oo aadan ku xirin fiilooyinka TX, ama waxaad isticmaali kartaa shabakad aan lahayn IP (iyo DHCP-la'aan) oo aan haba yaraatee gudbin baakadaha. Ugu dambeyntii ogow haddii aad rabto inaad isticmaasho tuubada si aadan u lumin baakadaha, markaa ha isku darin tilmaamaha ama ha isticmaalin badhanka halkaasoo tilmaamaha la taabtay ay ka gaabiyaan (tusaale 100 Mbit) dekedda isku-darka (tusaale 1 Gbit).
